PHILIP LESTRDE, OF NEW ORLEANS, LOUISIANA.

'rHiLL-TIUG.

` Specification of Letters Iatent.

Be it known that I, PHILIP Liis'iRADii, citizen of the United States, residing at New Orleans, in the parish of'Orleans and State of Louisiana, have invented newand useful Improvements in Thill-Tugs, o-f which the following is a specification.

. My present invention pertains to thilll tugs such as are equipped with anti-frict-ion devices for working yagainst the underside and the vertical sides of a thill or shaft; and it consists in they peculiar and advantageous thill tug hereinafter described in detail and definitely claimed.

, front elevation of the tliill tug constituting the best practical embodiment of my `invention that I haveas yet devised. Fig. 2 is a view showing the body of the tug insecti on and the buckle and loop ink elevation; the

' incidental to the use of the tug.

The tug body comprises two sections 1 of suitable metal, andthe said sections are connectedl together by rivets 2fand also by the pivot pin 3 of the buckle body 1, and the pivot pin 5 of the loop 6. In the edges vof the said body sections 1 are rabbets which when the sections are connected Las stated forma groove 7 that extends entirely around the body. It will also be observed that ren cesses 8 are formedin the opposed sides of the sections 1 at one end of thel device to receive and permit play ofthe buckle tongue `9, and that the-opposed sides of the sections y1 are recessednas indicated by 10 and 11 for the reception of the anti-friction balls 12and the ball trunnions 13, respectively,

whereby the balls or, more strictly speaking, rollers are enabled to turn backward l other.

In the accompanying drawings which are`r hereby'made a part hereof :f Figure 1 is a The yrollers 12 protrude into the central Fig. 1, and consequently ybear againstthe thill or shaft and render easy all movements of the tug or shaftwith respect vto each It will be gathered from the `foregoing that my novel 'tug is susceptible ofbeingy easily and cheaply produced, that it is yeX- ceediiigly strong and durable, and that'there is no liability of any one of the rollers k 12i being displaced until aftery the body sec tions 1 are disconnected and separated.` It will :also begathered that .a band or strap can be readily. connected to my novel tug direct, thisbecause of the groove 7 kin the edge of the body.

When desired of providing the rollers' 12 with vtruniiions 13, the said rollers may be loosely mounted on shaftsdl", disposed in therecessesll n ofther body sections 1- as shown in Fig. .4.

claimyand desire to secureby Letters-Pat# ent, is: K A thill tug comprising opposed body sections having registered thillereceiving openings and also having their edges Vrabbetedl to form a groove and furtherhaving registiered recesses in their opposed sides and smaller recesses iii said sides and in v`conimunication with the first named recesses, rollers disposed in the pockets formed by the first named recessesand protruding into the chill-receiving openings, roller support ing means disposed in theV second named recesses, pivot pins extending transversely through the sections, a-fbuckle body and av buckle tongue pivoted on vone of said pins,
